I = Industrial setting, ( ) = parameter
window text. [ ] = value for use in communication via serial communication port
215 Preset reference 1 (PRESET REF. 1)
216 Preset reference 2 (PRESET REF. 2)
Settings:
-100.00 % - +100.00 % [-10000 - +10000]
% of the reference range/external reference
✭ 0.00% [0]
Function:
Tw o different preset references can be programmed
in parameters 215-216.
The preset reference is stated as a percentage of
the value Ref
MAX
or as a percentage of the other
external references, depending on the choice made
in parameter 214. If a Ref
MIN
≠ 0 has been
programmed, the preset reference as a percentage
will be calculated on the basis of the difference
between Ref
MAX
and Ref
MIN
, following which the
value is added to Ref
MIN
.
Description of choice:
Set the fixed reference(s) that is/are to be the
options.
To use the fixed references, it is necessary to have
selected Preset ref. enable on terminal 2, 3, 4, or 5
(parameters 332 - 335).
Choices between fixed references can be made by
activating terminal 2, 3, 4, or 5 - see the table
below.
Terminals 2/3/4/5
Preset reference
Preset reference 1 0
Preset reference 2 1
219 Catch up/slow down value
(CATCH UP/SLW DWN)
Settings:
0.00 - 100.00 % [0 - 10000]
✭ 0.00 % [0]
Function:
This parameter enables the entry of a percentage
value (relative) which will either be added to or
deducted from the actual reference.
Description of choice:
If Catch up has been selected via one of the
terminals 2, 3, 4, or 5 (parameters 332 - 335), the
percentage (relative) value selected in parameter
219 will be added to the total reference.
If Slow down has been selected via one of the
terminals 2, 3, 4, or 5 (parameters 332 - 335), the
percentage (relative) value selected in parameter
219 will be deducted from the total reference.
221 Current limit for motor mode
(CURRENT LIMIT)
Settings:
Min. limit (XX.X) - max. limit (XXX.X)
in % of I
RATED
[XXX - XXXX]
✭ Max. limit (XXX.X) [XXXX]
I
RATED
= rated motor current
Min. limit = magnetizing current in % of I
RATED
Max. limit = unit dependent limit in % of I
RATED
Function:
This function is relevant for all application
configurations; speed and process regulation. This is
where to set the current limit for motor operation.
